Patriot Viper Xtreme 5 DDR5 RAM 48GB (2X24GB) 8200MT/s CL38 UDIMM Desktop Gaming Memory Kit - PVX548G82C38K

The memory modules have their own heatsinks with a red finish which looks good in the case. They were easy to fit in and the speed is excellent. These support XMP 3 so be sure to enable this in your bios if supported to ensure maximum performance.

In Asus Apex Encore Z790 I would get constant lock ups and crashes with 8000mhz and 7800mhz setting, XMP II/XMP Tweaked or manual settings. My Apex Encore is arguably best board on the market for this too. Only rivaled by previous Z790 Apex (white version).I have Team Group 8000mhz, and they easily run at those frequencies, you have to tune them, but even at 8000mhz I will not get the lock up, but only 1 error with Test Mem 5 with XMP II profile with Team Group.Patriot will give errors and lock ups before I even get to comfortable Test Mem 5 run.

Es algo de locos lo que ocurre con estos módulos de memoria, si lo pones a pelo con los perfiles de XMP desactivados trabajan bien a 5.000Mhz, pero como actives los perfiles XMP 1,2, 3 o tweaked el PC no llega ni a encender la BIOS, salta el SAI con error de cortocircuito "FAULT", desactiva la fuente de entra y salida del SAI y se apaga todo PC y SAI, no lo había visto nunca.Mi placa base es una ASUS Fórmula de gama alta, me quedo con mis Kingston Fury que jamás me han dado problemas.No las recomiendo.

Ottime RAM e facilmente riconosciute dalla mia scheda madre Asus x670e.Arrivano tranquillamente alla velocità dichiarata di 8200mhz con i setting consigliati.Se non badate a fronzoli, lucine e menate varie direi che a questo prezzo (220€) sono un ottimo affare anche a livello di performance.Da qui a breve queste RAM saranno una base da avere per i nuovi processori AMD ryzen serie 9000.Consigliatissimo e ottimo rapporto prezzo prestazioni.

I paired this with an Asrock Z790i lightning board and a SP109 14900KS.Testing XMP (1.45v) as is resulted in errors running TM5 at 8000 and 8200 within 15 and 5 minutes respectively on a standard "Universal 2" 90 minute run.Manually testing with loose timings at 1.45v and 1.40v at both 8000 and 8200 again resulted in errors running TM57800 was stable at XMP and loose timings TM5 90 minute test.Testing how high these will boot, they would not even register at 8400 and required a manual reset.I ordered a pair of Teamgroup Xtreem 2x24GB 8200 sticks to verify my findings above and see if it was the memory, CPU, motherboard, user error or a combination thereof. Turns out it was the Patriot memory.Using the Teamgroup sticks, I was able to pass 8000 and 8200 TM5 full 90 minute run at 1.40v and 1.45v XMP in the exact same hardware setup. I'm still dialing in and testing the Teamgroup sticks, but they even booted up at 8600 so that's a future project.I must also make note of the absolutely cheap and shoddy heatsinks the Patriot sticks use compared to the Teamgroup sticks. They are the thinnest and cheapest heatsinks I've encountered yet on DDR5 sticks. Placing them on a scale, the Patriot sticks weighed ~47g/ea while the Teamgroup sticks were 84g/ea and it showed in the build quality and looks. Both were non-RGB. Yes, the Teamgroup sticks do cost more (~$70USD more), but you get what you pay for sometimes.Both are SK Hynix M die. Binning matters.Temperatures were not the problem as the Patriot sticks failed before even reaching 55c at 1.45v which is their rated Vmem. Running them at 7800, temps hit 70+. The Teamgroup sticks hit ~70c peak and still passed.

title says It all. Tried after market heat sink and an aftermarket ram fan and still won't stay stable on xmp1 or even xmp2
